DNS Setup through ZPanel

Hi, just curious if this setup looks correct to you guys (I'm using Digital Ocean's Nameservers, but not setting it up through the VM Control Panel):
A Records:
@ [IP Address of Droplet]
mail [IP]
MX Record:
@ 10 mail.exampledomain.com
NS Records:
@ [ns1.digitalocean.com]
@ [ns2.digitalocean.com]
@ [ns3.digitalocean.com]
I also have my domain registrar pointing to the three name servers listed above.
It's coming back "Query Refused" but I'm not sure if that's just left over from the mess I created yesterday.
Thanks ahead of time,
Nate.
